THOMAS \V. JENKINS, OF PHILADELPHIA, PENNSYLVANIA.

DEVICE FOR FEEDING SHAVlNGS, &o., TO FURNACES.

SPECIFICATION forming part of Letters Patent No. 307,552, dated November 4, 1884:.

Application filed Deccmher 20, 1883. (No model.)

To all who/2t it may concern:

Be it known that I,,THOMAS W. J nxxrNs, a citizen of the United States, residing in the city and county of Philadelphia, State ofPennsylvania, have invented a new and useful Improvement in Devices for Feeding Shavings, &c., to Furnaces, which improvement is fully set. forth in the following specification and aecompanying drawings, in which Figurcl represents a vertical section of a burner for shavings, the, embodying my invention in line as :r, Fig. 2. Fig. 2 represents a vertical section thereof in line i 7 Fig. 1.

Similar letters of reference indicate corre sponding parts in the several figures.

My invention consists of a fuel-receiving hopper provided with a valve, in combination with a box communicating with said hopper, and an injector communicating with said box, said valve serving to direct the fuel to the injector and adjust the flow thereof.

It also consists of a combination with the furnace of a deflector and a depending wall, as will be hereinafter set forth and claimed.

Referring to the drawings, A represents a hopper which is open or partly open at the bottom, and'properly supported over a box or chamber, B, with which it communicates, the hopper having at the bottom a valve or gate, 0, whereby the communication with the box B may be opened or closed. \Vithin the hopper is a series of paddles, vanes, or heaters, 1), whose shaft D is mounted on a step, 1), and rotated by any suitable power.

Attached to the box 13 is an injector, E, or generator of vapor of steam and air which is in communication with the box, and a conveying-pipe, F, the latter leading into a .furnacc, of which any desired form maybe employed. The hopper is properly supplied with light fuel-such as shavings, sawdust, woodcuttings, &c.and power imparted to the shaft 1), so as to rotate the paddles D, thus preventing choking of the fuel. The gate 0 being open, permits the fuel to pass through the bottom outlet of the hopper and enter the box 13, it being noticed that said gate is adapted to adjust the flow of the fuel, and may be set to direct the fuel toward the mouth of the injector E, said mouth being opened to admit air thereinto. A pipe leading from a suitable source ofsteam is connected with injector, and

I so that steam enters the injector and eommingl'es with the air admitted thereinto in such manner as to generate a combustible vapor, which is forcibly impelled into the pipe F. The fuel reaching the mouth of the injector is drawn into the injector and pipe'F, and conveyed by and with the vapor into the furnace, where both are burned, the combustion being rapid and more perfect than ordinary, whereby sparks and smoke are prevented and greater heat is attained. The fuel which fails to enter the injector drops into the box B, from whence it is removable through the door B, and may be thrown again into the hopper.

G represents an arch or wall, which depends from the furnace near the end of the same, adjacent to the flue, or at the extreme end of the conibustion-ehamber, thus forming a reverberatory furnace, serving as a check to the rapid discharge of the light fuel injected into the furnace, whereby as said fuel is retained a longer period of time in the furnace it is properly consumed, thus preventing sparks, consuming smoke, and intensifying the heat.

In order to prevent the fuel being forced through the grate, I employ a deflector, H, which is located on the grate below the dis charge end of the conveyingtubc, whereby as the fuel is impelled against the deflector it is diffused over the grate without liability of choking the grate-bars or packing thereon.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A fuel-receiving hopper provided with a valve, in combination with a box communicating with said hopper, and an injector communicating with said box, said valve serving to direct the fuel to the injector and adjust the flow thereof, substantially as and for the purpose set forth.

2. A fuel-receiving hopper provided with a valve, in combination with a box OOITllDll nicating with said hopper, and an injector communicating wit-h said box, said valve serving to direct'the fuel to the injector and ada depending Wall withintheeombnstion-chamjust the flow thereof, and said box having 1t door, B, substantially as and for the purpose 1 pose set forth.
